Objective: To determine the extent to which coping strategies mediate chronic low back pain (CLBP) disability in patients presenting for physiotherapy.
Subjects: CLBP patients presenting for their first assessment at an outpatient physiotherapy department were used (N = 90; 60% male; M age = 41 yrs; SD ± 10).
Design: The mediating role of coping strategies was investigated after controlling for the influence of recorded demographics, healthcare variables and pain. Hierarchical multiple regression was employed with disability1 as the dependent variable. Independent variables were entered in three separate steps. Demographics (sex, age and socioeconomic status) were entered in Step one. Healthcare and Pain variables (leg pain, previous surgery, history of back pain and current pain intensity [VAS]) were entered in Step two. Three coping dimensions (Adaptive Coping, Maladaptive Coping and Efficacy of Pain Management), derived from a factor analysis of the Coping Strategies Questionnaire2, were entered in the final Step.
Results: Demographics accounted for 14% of the variance in disability [F (3, 86) = 4.81, P =. 004]. Healthcare and Pain variables accounted for an additional 17% of the variance [F (4, 82) = 5.11, P =. 001]. The three coping dimensions accounted for a further 6% of the variance [F (3, 79) = 2.71, P =. 05]. The model accounted for 38% of the variance in disability [F (10, 79) = 4.81, P =. 000].
Conclusion: Coping did mediate levels of CLBP disability. Moreover, disability is influenced more by Adaptive (Standardised β = −. 26, P =. 02) and Maladaptive (Standardised β =. 27, P =. 02) coping strategies than Efficacy of Pain Management (Standardised β =. 07, P >
. 05).
